The observations are assumed to be generated under the semi-parametric random censorship model (SRCM), that is, a random censorship model where the conditional expectation of the censoring indicator given the observation belongs to a parametric family. Under this setup a semi-parametric estimator of the survival function was introduced by the author. If the parametric model assumption is correct, it is known that the estimated functional which is based on this semi-parametric estimator is asymptotically at least as efficient as the corresponding one which rests on the nonparametric Kaplan-Meier estimator. In this paper we show that the estimated functional which is based on this semi-parametric estimator is asymptotically efficient with respect to the class of all regular estimators under this semi-parametric model.}, language = {en} } @inproceedings{DuongStaat2014, author = {Duong, Minh Tuan and Staat, Manfred}, title = {A face-based smoothed finite element method for hyperelastic models and tissue growth}, series = {11th World Congress on Computational Mechanics (WCCM XI) ; 5th European Conference on Computational Mechanics (ECCM V) ; 6th European Conference on Computational Fluid Dynamics (ECFD VI) ; July 20-25, 2014, Barcelona}, booktitle = {11th World Congress on Computational Mechanics (WCCM XI) ; 5th European Conference on Computational Mechanics (ECCM V) ; 6th European Conference on Computational Fluid Dynamics (ECFD VI) ; July 20-25, 2014, Barcelona}, editor = {Onate, E.}, organization = {World Congress on Computational Mechanics <11, 2014, Barcelona>}, pages = {1 -- 12}, year = {2014}, language = {en} } @inproceedings{EdipGarevskiButenwegetal.2014, author = {Edip, Kemal and Garevski, Mihail and Butenweg, Christoph and Sesov, Vlatko and Bojadjieva, Julijana and Gjorgjiev, Igor}, title = {Boundary effects on seismic analysis of multi-storey frames considering soil structure interaction phenomenon}, series = {Seismic design of industrial facilities : proceedings of the International Conference on Seismic Design of Industrial Facilities (SeDIF-Conference) ; [Aachen, 26. - 27.

Therefore, historical water channels in inner-Alpine dry valleys were used as century-long irrigation experiments to investigate adjustments in tree growth to contrasting water supply. This involved quantifying the tree-ring growth of irrigated and non-irrigated (control) Scots pine (Pinus sylvestris L.) in Valais (Switzerland), as well as European larch (Larix decidua Mill.) and black pine (Pinus nigra Arnold) in Vinschgau (Italy). Furthermore, the adjustments in radial growth of Scots pine and European larch to an abrupt stop in irrigation were analyzed. Irrigation promoted the radial growth of all tree species investigated compared to the control: (1) directly through increased soil water availability, and (2) indirectly through increased soil nutrients and humus contents in the irrigated plots. Irrigation led to a full elimination of growth responses to climate for European larch and black pine, but not for Scots pine, which might become more sensitive to drought with increasing tree size in Valais. For the control trees, the response of the latewood increment to water availability in July/August has decreased in recent decades for all species, but increased in May for Scots pine only. The sudden irrigation stop caused a drop in radial growth to a lower level for Scots pine or similar level for larch compared to the control for up to ten years. However, both tree species were then able to adjust to the new conditions and subsequently grew with similar (Scots pine) or even higher growth rates (larch) than the control. To estimate the impact of climate change on future forest development, the duration of manipulation experiments should be on longer time scales in order to capture adjustment processes and feedback mechanisms of forest ecosystems.}, language = {en} } @article{FredebeulKreinSteingroever2014, author = {Fredebeul-Krein, Markus and Steingr{\"o}ver, Markus}, title = {Wholesale broadband access to IPTV in an NGA environment : how to deal with it from a regulatory perspective?}, series = {Telecommunications Policy}, volume = {38}, journal = {Telecommunications Policy}, number = {3}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0308-5961 (Print)}, doi = {doi:10.1016/j.telpol.2013.04.002}, pages = {264 -- 277}, year = {2014}, language = {en} }
